Method and System for Managing Mobile Management Entity (mme) in a Telecommunication Network

1. A method of transmitting a bearer resource request message from a UE over a plurality of relay node to a mobility management entity for setting up an EPS bearer in an LTE Network, the method comprising: receiving the bearer resource request message at the MME_UE from the UE, wherein the bearer resource request message is corresponding to the UE's original bearer resource request; inspecting the received message by the MME_UE in order to identify presence of RN_ID, if any; requesting to receive by the MME_UE from the MME_RNs for RN's ‘management context information’ wherein management context includes all information that enables taking over the function of MME_RN by the MME_UE; and consolidating the MME_UE and MME_RNs function within the MME as MME_UE_RNs, so that for all future response to the received request will be managed by MME_UE_RN.

2. The method of claim 1 , wherein the received bearer resource request message includes bearer resource request for UE and the relay node IDs.

3. The method of claim 1 , further comprising: notifying all the MME_RN to terminate managing of the relay nodes in the network path of the UE once RN's management context information is received.

4. The method of claim 1 , further comprising: preparing to take over the function of MME_RNs by the MME_UE.

5. The method of claim 1 , wherein all the relay nodes IDs are encapsulated in the UE resource request message to MME.

6. The method of claim 1 , wherein the MME_UE_RN manages both UE and RN and checks if RN has the capability to support additional bearer service.

7. A system of transmitting a bearer resource request message from a UE over a plurality of relay node to a mobility management entity for setting up an EPS bearer in a LTE Network, the system comprising: at least one UE; a plurality of Relay Nodes; at least one enode B; and a mobile management entity includes a processor configured for receiving the bearer resource request message at the MME_UE from the UE, wherein the bearer resource request message is corresponding to the UE's original bearer resource request; inspecting the received message by the MME_UE in order to identify presence of RN_ID, if any; requesting to receive by the MME_UE from the MME_RNs for RN's ‘management context information’ wherein management context includes all information that enables taking over the function of MME_RN by the MME_UE; and consolidating the MME_UE and MME_RNs function within the MME as MME_UE_RNs, so that for all future response to the received request will be managed by MME_UE_RN.

8. A node, comprising a processor including a memory; and a network protocol module coupled to the processor, wherein the processor is configured for: receiving the bearer resource request message at the MME_UE from the UE, wherein the bearer resource request message is corresponding to the UE's original bearer resource request; inspecting the received message by the MME_UE in order to identify presence of RN_ID, if any; requesting to receive by the MME_UE from the MME_RNs for RN's ‘management context information’ wherein management context includes all information that enables taking over the function of MME_RN by the MME_UE; and consolidating the MME_UE and MME_RNs function within the MME as MME_UE_RNs, so that for all future response to the received request will be managed by MME_UE_RN.

9. The node of claim 8 is a Mobile Management Entity including MME_UE and MME_RN.
